Question

Hey.
I’ve got a QListView, and so far I’ve only figured out how to use the signals that are already given. I can’t find any signals for when the enter key was pressed on an item in the list (QStandardListItem). Can’t seem to find any keyPressedEvents either.

Is it possible to “hook up” QListView to a event just like that? How? 🙂

Thanks

Use event filtering: e.g. in the list container’s setupUi, do

# the self param passed to installEventFilter indicates the object which
# defines eventFilter(), see below:
self.list.installEventFilter(self)

and then define the filter API function in that container:

def eventFilter(self, watched, event):
    if event.type() == QEvent.KeyPress and \
       event.matches(QKeySequence.InsertParagraphSeparator):
       i = self.list.currentRow()
       # process enter key on row i

Note that InsertParagraphSeparator is the logical event bound to the Enter key. You can use alternative ways of catching the event, but what I have shown should point you in the right direction.
